1 HSSE TAP line 1/11

2 2/11 HSSE TAP line FEATURES HSS-E: High speed steel with cobalt for increased wear and heat resistance Universal application solution for steel, stainless steel and cast iron High cutting speed with low cutting force Longer tool life credit to optimized cutting geometry and the option of either TiN coating or steam tempering Excellent thread quality for both ISO standard and fine threads via 2 different flute geometries for through and blind-hole applications Now available from TaeguTec, a new line of taps that provide a total metal cutting solution. This new line of High Speed Steel cobalt taps expands the threading range of TaeguTec beyond milling and turning applications with carbide tools to High Speed Steel. Whether its metric ISO standard or fine threads, the new line offers 2 different flute geometries for both through and blind-hole applications. Optimized cutting geometry means application to a wider range of materials and ensures easy chip evacuation which translate into precision machining with process reliability. Further enhancing the new line, each geometry comes in 3 different grades; uncoated, steam tempered or TiN coated which enable higher productivity and economy on a wide range of materials. This standard line covers the ISO 2-6H tolerance range.

4 Right hand spiral flute, 40 4/11 Features HSS-E taps for blind hole thread Straight flute, 40 helix angle Form C (2-3 threads chamfer) Dimension range: M2 M20 MF8X1.0 - MF16X1.5 ISO 2-6H tolerance Uncoated, steam tempered, TiN coated Best option for blind holes Tap designed with spiral flute grinding Spiral flute forces the chips out of the hole Flute is optimally designed for both cutting fluid and chip evacuation The application Right hand spiral flute for blind hold thread Blind hole depth of thread up to 2XD Blind hole depth of thread up to 3XD

5 Grades features 5/11 Universal use in different materials Uncoated Economical choice Recommended for steel up to max. 800N/mm 2 Steam Tempered Ferric oxide layer at the cutting edge Better chip flow and reduced built-up edge means increased tool life TiN coated PVD titanium nitride layer High hardness, chemical stability and heat resistance Low heat conductivity and smooth operation at low cutting speeds Universal application on a wide range of materials Longer tool life credit to balanced characteristics Chamfer The tap chamfer is the tapering of the threads to distribute cutting action over several teeth. It generally reduces cutting forces, increases tool life and allows higher cutting speed. When the tap enters the hole and begins to cut, each tooth in the chamfer gradually enlarges the thread in the part. Only the first full thread behind the chamfer produces the finished size of the thread. The teeth beyond the first full thread serve to guide and support the tap as it creates the desired complete threaded depth of the tapped hole. Chamfer lengths are selected based upon the type of hole to be tapped. Long thread chamfer: Through hole Blind hole with sufficient room at the bottom Short thread chamfer: Thread to the bottom of blind hole Form A Form B Form C Form D Form E Form F 5-6 Threads 4-5 Threads 2-3 Threads Threads Threads Threads
